【摘要】 针对浅层软土中埋设的矩形截面地下综合管廊进行了非一致地震激励下的振动台模型试验研究。作为首个此种类型结构非一致激励的振动台试验工作,本文主要介绍试验方法,重点包括试验方案设计、开洞试验模型箱与模型结构设计,根据试验的特殊要求而开发的土体滑移传感器和地下结构接头位移测量装置,以及人工合成输入地震波动时程的方法与步骤。上述试验设计方法可供今后类似试验工作参考。试验结果分析及数值模型验证结果将在后续系列论文中介绍。更多还原

【Abstract】 A series of shaking table tests were conducted on scaled utility tunnel model with or without construction joint under non-uniform input earthquake excitation.Being the first shaking table test on utility tunnel with consideration of non-uniform excitation,details of experimental setup are first presented with special focuses on: design and fabrication of double-axis laminar shear box with a rectangular hole opened on its side walls;design fabrication of structural model with or without joint;design and verification of two devices for measuring the slippage between the interface of model ground and the structure,and finally the procedure for construction of input earthquake ground motions.Details of experimental setup presented in this paper are useful for further similar test.更多还原
